In Pics: NASA alert as 5 asteroids set to make close approach to Earth
1/5 Asteroid 2022 WB5 - NASA’s Planetary Defense Coordination Office (PDCO) has issued an alert against an asteroid named Asteroid 2022 WB5. The 84 feet wide asteroid is expected to fly past Earth today, December 5, at a distance of 2.2 million kilometers. The asteroid is already on its way towards Earth, travelling at a staggering speed of 39471 kilometers per hour! (Pixabay)

What’s shocking is that the asteroid is nearly the size of a commercial aircraft, with a width of nearly 170 feet! The Asteroid 2022 VP1 is expected to make its closest approach to the planet at a distance of 6.6 million kilometers today at a speed of 25455 kilometers per hour, as per NASA. (Pixabay)

This asteroid, with a size between 72 feet and 160 feet, is heading for Earth at a blistering speed of 25843 kilometers per hour. It will miss Earth today at a close distance of 5.9 million kilometers. (Pixabay)
5/5 Asteroid 2022 WK9 – This week’s fifth asteroid, with a size ranging between 82 feet and 183 feet, is named Asteroid 2022 WK9 and will be making its closest Earth approach on December 7. It will come as close as 2.3 million kilometers, according to the information provided by NASA's Jet Propulsion Laboratory (JPL). And this is not all, the stadium-sized asteroid is also moving at a mind-numbing speed of 51504 kilometer per hour. (Flickr)

Two of the most prominent telescopes run by NASA, the Hubble Space Telescope and the James Webb Space Telescope, keep on clicking stunning images of stars, planets, and more that are out there in space. Recently the Hubble Space Telescope has clicked a beautiful image of an around 10-million-year-old open star cluster named NGC 1858. The cluster is a part of a satellite galaxy of our Milky Way and shows an abundance of star-forming regions. The image was shared by NASA on its Instagram account and by NASA's Marshall Space Flight Center on its Twitter account.

Taking to Instagram, NASA wrote in the caption, "An open star cluster northwest part of the Large Magellanic cloud, a satellite galaxy of our Milky Way, shows an abundance of star-forming regions. Open clusters are a type of star cluster with loose gravitational attraction between the stars, which causes the cluster to be more spread out and unusually shaped."

According to the space research organisation, NGC 1858 is also an emission nebula, which is a cloud of interstellar gas that has been ionized by ultraviolet wavelengths radiating off of nearby stars. The gas of the nebula emits its own light at visible wavelengths. In the image, the gas of nebula is seen as a faint cloud that populates the middle and bottom right of the image.

"The stars within this young cluster are at different phases of their evolution, making it a complex collection. Within NGC 1858, researchers have detected a protostar, a very young, emerging star, indicating that star formation within the cluster may still be active or has stopped very recently. The presence of an emission nebula also suggests that star formation recently occurred here, since the radiation required to ionize the gas of the nebula comes from stars that only live a short time," NASA added.

NGC 1858 is located about 160,000 light-years away in the constellation Dorado and contains multiple massive stars, which can be seen shining brightly throughout the center of the image. The cluster is located in a crowded area of the sky, and the large number of stars around the cluster makes it difficult to study alone.
